1, microscopic observation method, such as observing plant cell mitosis, observing chloroplast and cytoplasm flow, and observing plant cell plasma wall separation and repair experiment.

2. Color observation method, such as observing the inheritance of animal coat color and plant color.

3. Atomic synthesis methods, such as phage dipping experiment and carbon atom transfer pathway experiment.

4. The same group of experiments, such as wheat amylase catalyzed starch hydrolysis experiment, found auxin oat coleoptile experiment.

5. Adding creative methods, such as feeding method to study thyroid hormone and injection method to study animal insulin and growth hormone experiments.

6. Subtraction methods, such as castration and removal, are used to study sex hormones, thyroid hormones and growth hormones.

7. Hybridization experimental methods, such as Mendel's discovery of the genetic law of plant hybridization and testing of hybridization experiments.

8. Chemical analysis methods, such as selective absorption of calcium and silicon by tomatoes and rice, and extraction and separation of chloroplast pigments.
